The Australian Indicators Directorate and the Australian Cyber Safety Centre have joined cybersecurity establishments from the U.S., Canada, and New Zealand in warning native know-how professionals to watch out for menace actors affiliated with China, together with Salt Hurricane, infiltrating their crucial communications infrastructure.
The information comes weeks after the Australian Indicators Directorate’s Annual Cyber Menace Report 2023-2024, the place the company warned that state-sponsored cyber actors had been persistently focusing on Australian governments, crucial infrastructure, and companies utilizing evolving tradecraft over the latest reporting interval.
What’s Salt Hurricane?
Just lately, the U.S. revealed {that a} China-connected menace actor, Salt Hurricane, compromised the networks of no less than eight U.S.-based telecommunications suppliers as a part of “a broad and important cyber espionage marketing campaign.” However the marketing campaign shouldn’t be restricted to U.S. shores.
Australian companies didn’t affirm whether or not Salt Hurricane has reached Australian telco firms. Nonetheless, Grant Walsh, telco business lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and associate companies – would challenge such detailed steerage if the menace was not actual.”
“Telco networks have invested in a few of the most mature cyber defences in Australia. However the world menace panorama is deteriorating,” he wrote. “Telecommunications networks are a key goal for persistent and highly-capable state-based cyber espionage teams, notably these related to China.”

Salt Hurricane: A part of a wider state-sponsored menace downside
Over the previous yr, the ASD has issued a number of joint advisories with worldwide companions to focus on the evolving operations of state-sponsored cyber actors, notably from China-sponsored actors.
In February 2024, the ASD joined the U.S. and different worldwide companions in releasing an advisory. It assessed that China-sponsored cyber actors had been in search of to place themselves on info and communications know-how networks for disruptive cyberattacks in opposition to U.S. crucial infrastructure within the occasion of a serious disaster.
The ASD famous that Australian crucial infrastructure networks might be weak to related state-sponsored malicious cyber exercise as seen within the U.S.
“These actors conduct cyber operations in pursuit of state objectives, together with for espionage, in exerting malign affect, interference and coercion, and in in search of to pre-position on networks for disruptive cyber assaults,” the ASD wrote within the report.

Within the ASD’s annual cyber report, the company mentioned China’s alternative of targets and sample of behaviour is per pre-positioning for disruptive results somewhat than conventional cyber espionage operations. Nonetheless, it mentioned that state-sponsored cyber actors even have information-gathering and espionage aims in Australia.
“State actors have an everlasting curiosity in acquiring delicate info, mental property, and personally identifiable info to achieve strategic and tactical benefit,” the report mentioned. “Australian organisations typically maintain massive portions of information, so are doubtless a goal for the sort of exercise.”
Frequent methods utilized by state-sponsored attackers
In accordance with Walsh, China-sponsored actors like Salt Hurricane are “superior persistent menace actors.” Not like ransomware teams, they aren’t in search of fast monetary acquire however “need entry to the delicate core parts of crucial infrastructure, like telecommunications, for espionage and even harmful functions.”
“Their assaults will not be about locking up programs and extracting quick income,” in line with Walsh. “As an alternative, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect methods to get inside crucial infrastructure and keep there, doubtlessly for years. They’re ready to steal delicate information and even disrupt or destroy belongings within the occasion of future battle with Australia.”
The ASD has warned defenders concerning the frequent methods these state-sponsored menace actors leverage.
Provide chain compromises
The compromise of provide chains can act as a gateway to focus on networks, in line with the ASD. The company famous, “Cyber provide chain threat administration ought to kind a major factor of an organisation’s general cyber safety technique.”
Dwelling off the land methods
One of many causes state-sponsored actors are so troublesome to detect, in line with the ASD, is as a result of they use “built-in community administration instruments to hold out their aims and evade detection by mixing in with regular system and community actions.” These so-called “dwelling off the land” methods contain ready to steal info from an organisation’s community.
Cloud methods
State-sponsored menace actors adapt their methods to take advantage of cloud programs for espionage as organisations transfer to cloud-based infrastructure. The ASD mentioned methods for accessing an organisation’s cloud providers embody “brute-force assaults and password spraying to entry extremely privileged service accounts.”

How one can defend in opposition to cyber threats
There are some similarities in menace actors’ methods and the weaknesses within the programs they exploit. The ASD mentioned state-sponsored cyber actors typically use beforehand stolen information, equivalent to community info and credentials from earlier cyber safety incidents, to additional their operations and re-exploit community units.
Fortunately, firms can shield themselves from cyber-attacks. Earlier this yr, TechRepublic consolidated professional recommendation on how companies can defend themselves in opposition to the commonest cyber threats, together with zero-days, ransomware, and deepfakes. These recommendations included conserving software program up-to-date, implementing endpoint safety options, and growing an incident response plan.
